Guests, including Chief Secretary Eric Chan Kwok-ki and liaison office deputy head Chen Dong officiated at the ceremony.

All members of the uniformed groups marched into the venue with Chinese-style foot drills - also known as the “goose-stepping.”

Members of the Civil Aid Service’s Cadet Corps Guards of Honour and the Hong Kong Army Cadets were tasked as flag raisers and flag guards respectively.

Following the flag-raising ceremony, a representative of each uniformed group made a declaration and took an oath, saying they would love the country and uphold its sovereignty, love Hong Kong, and help open a new chapter for the city.

The May Fourth Movement in 1919 was sparked by a demonstration of university students in Beijing who gathered in Tiananmen Square to protest against the transfer of Chinese territories previously controlled by Germany to Japan.
